%description
A set of functions for analyzing the structure of forests based on the
leaf area density (LAD) and leaf area index (LAI) measures calculated from
Airborne Laser Scanning (ALS), i.e., scanning lidar (Light Detection and
Ranging) data. The methodology is discussed and described in Almeida et
al. (2019) <doi:10.3390/rs11010092> and Stark et al. (2012)
<doi:10.1111/j.1461-0248.2012.01864.x>.
